WATER-CLOSET SEAT.

Serial N 0. 723,709.

To all whom it may concern:

Be it known that I, HERMAN M. HonL- semen, a citizen of the United States, reslding in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvements in Water-Closet Seats, of which the following is a specification.

This invention relates to improvements in water closet seats.

One object of the invention is to provide a water closet seat of rigid construction which is composed of material that is im pervious and incorrodible, such as rubber, rubber compounds, cellulose, etc.,' and which may be made lastic and molded.

Another ob ect of the invention is to provide a water closet seat of the type above indicated, which will have embedded therein, a reinforcing or stren honing member of metal which will be ully protected from possibility of corrosion from water or vapor, said strengthening or reinforcing member preventing the seat from liabi ity of cracking or breaking from rough usage.

Other objects of the invention are to provide a water closet seat having a reinforcing or strengthening member embedded in the material forming the seat, which will have metal hinge lugs formed integrally with the reinforcing or strengthening member and also a seat composed of rubber or equivalent material which is provided with an ornamental, polished, veneer surface.

The invention furthermore consists in improvements in the parts and in the novel combinations of the parts as herein shown, described or claimed.

Hitherto water closet seats have been made of metal but the same have been found objectionable for the reason that they soon corrode and feel cold to the body. In other instances, water closet seats have been made of other materials which could be molded but which are not as strong as metal and are easily fractured or broken by rough handling. With my improvements the water closet seat possesses all the valuable properties inherent-with the use of such moldable materials as rubber, rubber compounds, etc., and has also the requisite strength to prevent liability of breaka e and yet is free from the objections resu ting from the use of metal.

In the drawing forming apart of this specification, Figure 1 is a plan view of a Watercloset seat embodyin my improvements. Fig. 2 is a bottom p an view of the seat shown in Fig. 1. Fig. 3 is a longitudinal, vertical sect-ion taken on the line 33 of Fig. 1. Fig. 4 is a transverse section taken on the line 4-4 of Fig. 1. Fig. 5 is an enlarged detail sectional view taken on the line 5-5 of Fig. 1, and Fig. 6 is a plan view showing my improvements embodied in what is commonly termed a crescent seat.

In said drawing the seat is denoted generally by the reference A, and as shown, is substantially convex on its upper side and concave on the lower side, and may be composed of any substance which is impervious and non-corrodible, such as, for instance, rubber, rubber compounds, cellulose, etc, which are adapted to be made plastic and easily molded. Embedded in the rubber 10 or other material com osing the seat, is a strengthening or st-i ening member 11, which as shown in Fig. 1, extends entirely around the seat, and as shown in Figs. 1 to 3 inclusive, the hinge lugs 12 for the seat, are made integrall with this strengthening member 11. In tliose instances where the seat is employed to automatically operate a flush valve, the flush-valve-operating.lever or projection 13 may be also formed integral with the stiffening or strengthening member 11, and in these instances connecting webs 14 are preferably employed between the hinge lugs 12 and the projection 13, which fit against the back edge of the seat.

The seat is made convex-concave, as above described, for two reasons, first to reduce as much as possible the amount of rubber or other compound used, and second to keep the seat raised from the top rim 15 of the water closet bowl inorder to allow the free circu- 'lation of air beneath the seat and thereby prevent the collection of moisture or foul matter therebeneath.

In order to keep the seat raised or spaced from the rim of the bowl, the seat is provided with rubber cushions 16 which are formed integrally with the material forming the seat, and in those cases where rubber or rubber compounds are employed, each cushion is vulcanized to the main body of the seat. thus forming a seat having cushions attached thereto without any cracks or slots in which might collect moisture or other undesirable matter. As more clearly shown in Patented Nov. 18, 1913.

- in'g operation.

' strengthening In Fig. '6,th e crescent 'seat B,'which may be 'com'posedfof rubber or other equivalent impervious, incorrodible substance has embedded therein, 'acrescent shaped strengthen ing'o'r stiffeningmember 111 of metal. In this form of 'seat'the' embedded stifiening or member highly "desirable, since otherwise the ends ofithe arms forming the crescent are quite likely to become broken or cracked in use, because of the fact that there'is no connecting port-ion'therebetween supported at a as inth'e ordinary ringJi-ke form of'seat. In the construction shown in Figbfi, the hinged lugs 112 are also preferably formed integral with the member 111, anda connecting web 114 is also provided betweenthe hinge lugs 112 Which'fits-the rear edge of the seat.

As shown in the drawings, the seat 10, is plurality of points, at the rear by the hinge connections, and at the fr'ontby the cushions 16, so that the seat is eld spaced'from the bowl 'fo'r the purpose hereinbe'fore described. The seat, being supported in this manner, will be subject tosevere bending strains between the points of sup ort by the Wei'ght'of'the'user, and the sti eningor strengthening members 11 and 111 inustbe made strong enough to Withstand thesebendinig strains, and as shown in the drawings, these members -11'and 111 are I provided on its upper sur- Vmade ofrelatively large bars rectangular in cross section.

From the foregoing description'it will be seen that I have provided a sanitary water closet seat which is free from undesirable cracks or joints such as are found in all wooden seats, and that the seat is thoroughly strengthened and stifiened substantially as rigidly as an all-metal seat, and yet which 1s free from all the disadvantages found in allmetal seats, and which is provided with a highly-polished or finished surface.

Although I have herein shown and described what I now consider the preferred embodiments of my invention, yet it will be obvious to those skilled in the art, that variouschanges and modifications may be made in'the details of construction without departing fromthe spirit of-the invention, and all such changes and modifications are contemplatedas come within the scope of the claims appended hereto.

'1 claim 1. A water closet seat of the character described, composed of rubber of an inferior grade and having a metal reinforcing member embedded therein, said seat being provided with an outer polished veneer surface of a better grade of rubber, substantially as specified.

2. Awater closet seat of the character def scribed, the main portion of which is composed of a plastic material of an inferior grade and having anouter, polished veneer surface of a better gradeofplastic material, said seat being substantiallyconcavmconvex in cross-section,- substantially as specified.
